Tektonska evolucija istočne periferije timočke eruptivne oblasti
Stefan Zujić (2024)U radu su predstavljeni rezultati proučavanja tektonskih i litostratigrafskih karakteristika istočnog oboda Timočke eruptivne zone. Zaključci o geološkim odnosima u okviru Timočke eruptivne oblasti i susednih geotektonskih jedinica izvedeni su na osnovu podataka prikuljenih tokom terenskih istraživanja i podataka dobijenih iz publikovanih radova. Rezultati rada ukazuju da je teren koji je bio tema ovog istraživanja, u strukturno-tektonskom smislu oblikovan tokom glavnih geodinamičkih događaja u okviru Karpato-balkanskog orogenog luka. Analizom strukturnog sklopa su utvrđeni glavni deformacioni događaji koji su predsavljeni ...Stefan Zujić. Tektonska evolucija istočne periferije timočke eruptivne oblasti, 2024

Анализа одрона у стенским косинама: савремени приступи
Милош Марјановић (2023)У Србији и региону познате су бројне појаве одрона које су изазвале велике застоје саобраћаја, материјалне штете или чак имале фаталне исходе, па их је потребно непрестано пратити и изучавати. Mодeловањe одрона скопчано је са ниским нивоом поузданости, али савремене технологије омогућавају да сe такви изгледи донекле побољшају. Једна од технологија која чини искорак утом правцу јe LiDAR-ско скенирање, које обезбеђује детаљне топографске подлоге у виду облака тачака високе резолуције и тачности.

Validation of vulnerability assessment by means of the Time Dependent, Model: case study from the Slovenian karst catchment
Groundwater vulnerability assessment methods are continuously being developed and existing methods are very often modified to provide better simulation of natural protection conditions and more objective results. Most frequently used methods are based on calculation of predefined parameters influencing water infiltration and underground flow, which can often lead to bias conclusions related to vulnerability evaluations. Some other methods, like the Time Dependent Model (TDM) are based on an approach, where parametrization is obtained at the final stage of the ...Ocena ranjivosti podzemnih voda, karstne podzemne vode, TDM metoda, delineacija sanitarnih zona, Slovenački karstVladimir Živanović, Nataša Ravbar, Igor Jemcov.

Determination of Mechanical Properties of Altered Dacite by Laboratory Methods
This paper presents a methodology for determining the uniaxial and triaxial compressive strength of heterogeneous material composed of dacite (D) and altered dacite (AD). A zone of gradual transition from altered dacite to dacite was observed in the rock mass. The mechanical properties of the rock material in that zone were determined by laboratory tests of composite samples that consisted of rock material discs. However, the functional dependence on the strength parameter alteration of the rock material (UCS, intact ...... material in this zone (extrusive igneous rocks) concluded that the alterations in the rock mass occurred gradually (Figure 1). Subsequent interpretation of geological structure (Figure 1) singled out three zones: altered dacite, transitional zone, and compact dacite. The transition zone represented the ...
... The first zone includes test results of dacite specimens (0% AD) and composite specimens with 10% and 30% volumetric participation of altered dacite. In this zone, the UCS-σci UCS and intact UCS- σci TX decreases exponentially from the initial value (100%) to around 37%. In the second zone, the composite ...

Tectonic evolution of the Vršac Mts. (NE Serbia): Inferences from field kinematic and microstructural investigations
The Vršac Mts. in NE Serbia represent the key area to investigate structural relations between the Northern Serbo-Macedonian Subunit and Supragetic Unit of the Dacia Mega-Unit. The geodynamic events during the Variscan orogeny in the Late Paleozoic colligated the two units and led to their metamorphic differentiation. The Late Cretaceous extension exhumed the medium-grade Serbo-Macedonian metamorphic rocks and structurally juxtaposed them against the low-grade metamorphosed basement of the Supragetic Unit along an E-dipping shear zone, which outcrops in the ...severna srpsko-makedonska subjedinica, supragetikum, kinematska analiza, multifazna ekstenzionalna deformacija... r i d o r M o r a v a V a l l e y C o r r i d o r Jastrebac Mts.Jastrebac Mts.
